Be it knownthat I, VISIDOR DRESDNER, a'citizenof the United States, residing at Brook lyn, county of Kings, and State of New York, have invented a new and useful Fur-Plucking- Machine, of which the following is a specification, reference being had to the accompa nying drawings, forming part ofthe same.

My invention has for its object to provide a machine that will be free from any tendency to pluck out the fur from a skinalong with the long hair thereof whilethe' said skin is undergoing treatment forthe removal of the latter.

In the accompanying drawings, Figure 1 is a top "view of a fur-plucking machine constructed according to my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a front elevation of certain parts thereof. Fig, 4 is an enlarged section on the line as on, Fig. 1; and Fig. 5 is a longitudinal section of one of the rollers comprised in the'machine.

a designates a bed plate upon which are erected standards Z; Z) b ,f containing bear ings for a mainshaft 0, having a'fast and a loose pulley c c secured thereon.

Secured to the shaft o'by means of setscrews is a bladed roller (1, consisting of two,

collar portions cl, between which extend arms d preferably four in'nu'mber, to which blades (Pare secured. Theseblades are formed with a concave recess along their outer edges, in

which are placed rodsl'of elastic material 01 A covering d of suitable material, preferably thin and flexible sheet metal, such as tin, in-

closes the rods cl and blades d and each blade, with its cover, is rigidly secured to an arm (1 by means of screws (2 If desired, the blades d may be dispensed with and the properly-formed outer edges of the arms d be employed in place thereof; but I prefer the construction described.

6 is a belt of any suitable elastic material, with which the blades (1 cooperate. It is supported by a series of rollers arranged in such a manner that the blades d when rotating will comein contact with said belt eand roll therewith with a gradually-increasiug-pressure contact between them beginning with a very light pressure, sufficient to engage the hairs'and not injure or hold the fur, and in- I creasing asthe rolling continues until the ;p'ressure is sufficient to grasp the hairs tightly enough to pluck them out. Preferably this belt is of rubber or other elastic material faced both-inside and outside with leather :cemented or otherwise secured to said elastic materiah 5 As here shown, there are three rollers e 6 a around which the belt e'is moved intermittentlylby the rotation of the blades CF. The roller 6 is arranged'above the shaft 0 in a perpendicular line therewith. The roller 8 is arranged more nearly adjacent to the blades (1 than the roller 6', so that as the blades 61 rotate they will engage the belt 6 and then compress it gradually from the time they are in line with the roller e until they are in line with the roller 6 The roller 6 isarranged to support the upper portion of the belt and is provided with collars e to re tain the belt in position. The rollers'e and e are carried by standards f of a verticallyadjustable frame f The roller 6 is carried ,in arms f pivotally connected to the'stand- ,ards f by screws f ,*upon which the arms may be turned to adjust the position of the roller (2 for tightening the belt e. After ,proper'adjustment the arms arelocked in position by the screws f. Each of these three rollers comprisesaninnertube a, secured to its supports by set-screws, and an outer tube or sleeve 6 to rotate on the inner tube be tween said supports.

The inner tubes have closed ends to serve as oil-reservoirs and are provided with oilfeed holes e and outlet-holes e In this manner the sleeves e are kept constantly lubricated and by reason of their length and protected arrangement are rendered very durable and effective for high speed.

The standards f extend rearwardly and downwardly through supports a, erected upon the bed-plate a, and are rigidly secured to a cross-bar f This crossbar f is pivotally eonnected to a lever f fulcrumed at f? and having its free end connected by a link f to a foot-lever f fulcrumed atf'.

f are coil-springs to supportthe standards in their proper normal position, which may be adjusted by nuts f. By means of this foot-lever I am enabled to readily and temporarily apply increased pressure to compensate for any inequality in the nature of the skins undergoing treatment.

g is a plate bent substantially as shown and is rigidly secured to the standards 1) 19 Its upper straight edge is in close proximity to the blades (1 and serves, chiefly, to protect the hands of the operator and aid somewhat in preventing the fur portion of the skin from being drawn in between the belt and blades.

h is a vertically-adjustable arm connected to a support h, forming part of a slide-carriage 7L2. This carriage comprises two rods 72 its, working in bearings 7L and having at their front ends a cross-bar h secured thereto. By this arrangement the skins may be inserted from the side around the free end of the arm h, thus affording means for handling them with facility and expedition. Arms h are secured to the rods 72, and have their lower ends mounted to slide on stationary rods 72. secured to the frame of the machine.

71 h are stops to limit the to-and-fro motion of the carriage 72/ 2' is a spring secured to the frame of the machine and serving to move back the carriage 71 against the stops 7L8.

j is a roller journaled in suitable bearings attached to the arm h.

An ordinary pneumatic exhaust-pipe It may be arranged in the rear of the blades (1 and belt 6 to carry off the plucked-out hairs.

In operation both ends of the skin are I grasped by the hands of the operator and inserted between the supporting-rollerj and the bladed roller. The carriage k is then pushed toward the machine by the body of the operator pressing against the cross-bar 72?. The operator then draws the skin upwardly and downwardly over the roller j, during which time the long projecting hair portions of the skin will be lifted up by the upward motion of the rotary blades and be seized between the belt 6 and the rotary blades with sufficient pressure to pluck them out, while the fur portion of the skin will be unaffected, as before described.

I claim- 1. The combination of a bladed roller, a belt of elastic material which is moved intermittently by the rotation of the blades of said roller, and rollers supporting the said belt and arranged to cause the said blades to bear against the belt with a gradually-increasing pressure during the time they roll in contact together, substantially as described.

2. The combination of a bladed roller, a belt of elastic material which is moved intermittently by the rotation of the blades of said roller, and rollers supporting the said belt, one of said rollers being arranged above the shaft of the bladed roller in a perpendicular line therewith, and another of said rollers being arranged in closer proximity to the blades than the latter, whereby as the blades rotate they will engage the belt and compress it gradually from the time they are in line with the first-mentioned roller until they are in line with the last-mentioned roller, substantially as described.

3. The combination of a bladed roller, an elastic belt and rollers supporting the same, said rollers comprising an inner perforated tubular oil-receptacle secured'by set-screws in supports and an outer sleeve fitted to rotate on the said inner tube between the sides of the supports, one ofsaid rollers being adjustable toward or from the other rollers and provided with collars to tighten and retain the belt in position, substantially as described.

4. In combination, a bed-plate, standards erected thereon, a bladed roller mounted in said standards; an elastic belt supported by rollers and cooperating with said bladed roller; Vertically-adjustable standards for carrying the belt-supporting rollers, secured in bearings formed in the'bed-plate and united by a cross-bar; springs controlled by stopnuts to press the standards upwardly; a footlever adapted to move the same downwardly, and a supporting-roller for the skin mounted in an arm secured to one side of a sliding carriage and open to admit skinssidewise around its free end, substantially as described.

5. In combination, a bladed roller, an elastic belt cooperating with said roller, a carriage comprising two slide-rods united by a cross-bar and working in fixed bearings; arms secured to said slide-rods and adapted to slide on stationary rods provided with adjustable stops; a spring to move the carriage in one direction, and a skin-su pportin g roller mou nted on the free end of an arm secured to one of the said slide-rods, substantially as described. v

6. A bladed roller consisting of two collar portions between which extend arms to which blades are secured, said blades being formed with a concave recess along their outer edges in which are placed rods of elastic material inclosed by a flexible cover, substantially as described.
